The government discovered that the deceased in the corpse dismemberment case was related to Jizhou Academy and asked Cheng Mufei to identify the body. Duan Yu and Gu Qingqiao went together.Cheng Mufei confirmed that the corpse was that of Mrs. Xu, who took care of his wife. However, his action of covering up the corpse's red eyes and death from blood magic was caught by Gu Qingqiao. This led Gu Qingqiao and Duan Yu to determine that several bizarre incidents were related to Cheng Mufei, and decided to join forces with Siyan to investigate the matter.thing.It turns out that Mrs. Xu died because of Xue Niang, and Duan Shaoyi was imprisoned by Cheng Mufei because he encountered Xue Niang performing blood magic.Xue Niang became ill again, and Lu Zizheng forced Cheng Mufei to hurry up and get the treasure map in Duan Yan's hand.Cheng Mufei was forced to take action, but he didn't know that Duan Yan was already prepared.Duan Yan and Cheng Mufei dealt with each other, while Duan Yu and Gu Qingqiao rescued Duan Shaoyi from the dungeon, mistakenly thinking that Xue Niang was also a victim, and rescued them together.Xue Niang did not want to implicate Cheng Mufei, so she used blood magic to break free, blocking Duan Yan's death with one move for Cheng Mufei.But when Gu Qingqiao revealed the truth that Bi Luozhu% was actually poison, Cheng Mufei felt regretful.Cheng Mufei's chess piece was no longer effective, so Lu Zizheng took the academy students as hostages and threatened Duan Yan to give away the treasure map. Gu Qingqiao took advantage of everyone's discussion to run alone to face the masked leader of the Holy Blood Sect.When Gu Qingqiao faced the sect master, he deliberately delayed time and looked for an opportunity to launch his sleeve arrows. The sleeve arrows pierced the sect master's hat, exposing the Meridian Gate on his neck.
